What is a PAN?
A PAN Number Validator checks whether a 10-character string matches the official format the Indian Income Tax Department uses for Permanent Account Numbers: 5 uppercase letters, followed by 4 digits, followed by 1 uppercase letter (e.g. ABCDE1234F). PAN is one of the most widely required identifiers in Indian finance, needed for filing income tax returns, opening bank accounts, registering high-value transactions, and much more, which makes catching a typo before submission genuinely useful.
This tool checks structure only. The PAN Validator confirms a string follows the correct format; it does not (and cannot, from a browser alone) confirm the PAN is actually registered with the Income Tax Department or belongs to a real person. Only the official e-filing portal can verify that.
Why Use a PAN Validator?
A single transposed digit or letter in a 10-character PAN is easy to miss when typing it into a form, but the consequences, a rejected application, a failed KYC check, a bounced bank transaction, are disproportionately frustrating compared to the simplicity of the mistake. Catching the format error immediately, before submission, saves a round trip of rejection and resubmission.
It's also useful for businesses and accountants who handle PAN numbers from many different people, quickly checking that an entry is structurally valid before it goes into a payroll system, vendor database, or tax filing helps catch obvious data-entry errors early.
Who Should Use This Validator?
Accountants and tax professionals check client-submitted PAN numbers for obvious format errors before using them in filings. HR and payroll teams validate employee-submitted PAN numbers during onboarding, since an incorrect PAN can cause TDS (tax-deducted-at-source) certificate mismatches later. Developers building KYC or onboarding forms for Indian fintech products use the same format rule programmatically and can use this tool to test their implementation. Individuals double-check their own PAN card details when filling out a form, especially if copying the number from a slightly worn physical card.
Pair this with the Income Tax Calculator when you're working through tax filing prep, or the Email Validator for checking other common identifiers used in the same forms.
What Insights Does the PAN Validator Give You?
A Valid result confirms your PAN has the correct length (10 characters) and the correct character pattern (letters where letters belong, digits where digits belong). The details breakdown goes a step further, decoding the 4th character to tell you what type of holder the PAN was issued to, P for an individual, C for a company, H for a Hindu Undivided Family, and so on, which is a useful sanity check if you expected, say, an individual's PAN but the 4th letter suggests a company.
An Invalid result tells you specifically what's wrong, wrong length, or a character in the wrong position, rather than a generic "invalid format" message, so you can compare directly against your physical PAN card to find the discrepancy.
How to use this PAN calculator
- Type or paste the PAN number into the PAN Number field, letters are automatically treated as uppercase.
- Watch the Valid/Invalid badge update instantly as you type.
- Read the message for a plain-English explanation of the result.
- If valid, check the details breakdown to see what holder type the 4th character indicates.
- If invalid, compare the flagged issue against your physical PAN card to spot the specific typo.

Formula & Methodology
A PAN is validated against the pattern/^[A-Z]{5}[0-9]{4}[A-Z]$/, exactly 5 uppercase letters, followed by exactly 4 digits, followed by exactly 1 uppercase letter, with no other characters permitted. The 4th character of the first 5 letters carries semantic meaning per Income Tax Department conventions: | Code | Holder Type | |---|---| |P| Individual | |C| Company | |H| Hindu Undivided Family (HUF) | |A| Association of Persons (AOP) | |B| Body of Individuals (BOI) | |G| Government | |F| Firm | |T| Trust | |L| Local Authority | |J| Artificial Juridical Person | Valid example:ABCDE1234F, 5 letters, 4 digits, 1 letter, matching the pattern exactly. Invalid example:ABCD1234F, only 4 letters before the digits (9 characters total instead of 10), so the pattern fails to match.
